Which is the correct description of argon in the atmosphere?
Answer and explanation
Correct answer: It is a nearly permanent inert gas
Argon is a noble gas and is chemically very unreactive under ordinary atmospheric conditions. It is present in a small but fairly constant proportion of dry air, so it is grouped with the permanent gases. Nitrogen is the most abundant atmospheric gas, while oxygen is directly used in respiration. Therefore option C is correct, and the remaining descriptions confuse argon with other substances.
